Selection of daily distance variations (2002-2021) at Mount Etna (EDDV_2002_2021)

Selection of daily distance variations between two pairs of GPS benchmarks (EMGL-EMAL and EMEG-ESLN) located in the western flank of Mt. Etna during 2002-2021. (Format: two GPS daily distance variations separated by comma in meters).

The authors acknowledge the Technicians and Technologists of the INGV - Osservatorio Etneo (GPS Permanent Network) for enabling and improving the acquisition of raw GNSS data. We are grateful to F. Cannavò that provided distance daily variations between two pairs of GPS benchmarks during the time periods when the solution is not available in Literature.

This work benefits from funding of the INGV in the frame of the projects “Ricerca Libera 2021” and “IMPACT - a multidisciplinary Insight on the kinematics and dynamics of Magmatic Processes at Mt. Etna Aimed at identifying preCursor phenomena and developing early warning sysTems”.

本数据集收录了2002年至2021年间，位于埃特纳火山（Mt. Etna）西侧侧翼的两组GPS基准站（GPS benchmark）对——EMGL-EMAL与EMEG-ESLN之间的每日距离变化序列。数据格式为两组以逗号分隔的GPS每日距离变化值，单位为米。

作者感谢INGV-埃特纳观测站（Osservatorio Etneo）的GPS永久监测网（GPS Permanent Network）技术人员与技师，感谢他们支持并优化了原始GNSS（Global Navigation Satellite System）数据的采集工作。我们谨向F. Cannavò致谢，其在文献中尚无对应解算结果的时段内，为我们提供了两组GPS基准站间的每日距离变化数据。

本研究得益于INGV在"Ricerca Libera 2021"以及"IMPACT——多学科解析埃特纳火山岩浆过程的运动学与动力学，以识别前兆现象并开发早期预警系统"项目框架下提供的资助。
